* When env variables did not have trailing slash, directory creation
could fail.
* If .cache in $HOME did not exist cache would have been disabled.

This PR ensures that the genHash will be the same
whether the cl_cache is re-used or just created.
So it has to be regenerated after compilation
to make sure it's created with non NULL irBinary.
It also allows to cache debugDataBinary.
Minor: Rename NEO_PERSISTENT_CACHE -> NEO_CACHE_PERSISTENT in FAQ,
since this version is used in code.

This patch add new environment variables to control compiler cache.
Works as follow: If persistent cache is set driver check if NEO_CACHE_DIR
is set. If not then driver checks XDG_CACHE_HOME - If exists
then driver create neo_compiler_cache folder, if
not then driver checks HOME directory. If each NEO_CACHE_DIR,
XDG_CACHE_HOME and HOME are not set then compiler cache is disabled.
Current support is for Linux only.
